Application october i5, 1934, serial Nansen V17 Claims.

My invention relates principally to the holder and, particularly, to the clamping arrangement for securing a safety razor blade in a holder.

An object and feature of my invention is the employment of a pivotally mounted clamping plate which is pivoted on the base or supporting plate of a safety razor holder and the construcrktional features for operating the hinged clamping plate to engage a razor blade between the clamping plate and the supporting plate.

AnotherV feature of my invention relates to a mechanical device for exerting a pressure of the clamping plate on the blade tohold the blade snugly between the supporting plate and the clamping plate.

Another feature of my invention is a mechan ism for operating both the pressure device and the clamping plate by a screw extending longitudinally of the handle of the blade holder.

Another and further detailed object of my invention is having the supporting plate rigidly connected to a handle and at one end of this supporting plate hinging the clamping plate.

A screw extending through the handle and having an operating head may be rotated to raise or lower the clamping plate, this being done by an arm connected to a sliding sleeve, the arm being attached by a link mechanism to the clamping plate and swiveling this on its hinge until it may occupy a position at right angles to the supporting plate through rotating the clamping plate to this position.

A further detailed feature of my invention in connection with the pressing device is operating this directly by the screw to engage the clamping plate and pull this downwardly tightly on a blade, and also the feature of releasing the pressure device before the clamping plate may be tilted upwardly. In this connection the screw is provided with a stem extending through the supporting plate, the razor blade, and through a perforation, and engaging a groove in the clamping plate. The stem is provided with a head at the top to engage the clamping plate, this head being automatically released through the slot on the upward tilting of the clamping plate.

Other detailed features of my invention relate to the supporting of the blade between knife-like edges, the detail shape of the blade, this being provided with a center perforation for the stem of the pressure device with two transverse slots for engaging setting pins, these slots being connected to the end edge of the blade, each by a longitudinal slot, this slot accommodating at one end a stud on the supporting blade and the link mechanism for operating the clamping plate.

Another feature of the blade is providing end tabs or projections to facilitate lifting the blade for inserting and removing from the holder. 5

My invention is illustrated in connection with the accompanying drawings, in which:

ith the clamping plate in its open or elevated 20 position.

Fig. 7 is a section onthe line l-l of Fig. 5, showing the blade in plan with the supporting plate thereunder.

Fig. 8 is an elevation similar to Fig. 2 with the 25 clamping plate in its opened position and the blade removed.

In constructing my invention I utilize a handle structure Il which has a substantially circular hub section I2 with lateral ns i3. These 30 ns are to provide good finger grips. The ns are formed bulbous on the side edges I4, thus providing concave grooves l5 extending longi- -tudinally on each side of the hub portion i2.

This enables the fingers to readily grip the han- 35 dle. The upper end of the handle is, preferably, circular in cross section at I'B and is provided with a longitudinal slot il. The handle has an enlarged lower bore I8 and a reduced upper bore i9 with a shoulder 20 therebetween. The lower portion, at least, of the bore I8 is internally threaded as indicated at 2l.

The supporting plate 22, on which the razor blade is mounted, is formed integral with the handle and has a central perforation 23 there- 45 through. This clamping plate is provided with a guard 24 on each edge, the guard being in the form of a comb and having end or corner teeth 25, and intermediate teeth 25, the teeth in cross section being substantially as shown in Fig. e. There is a longitudinal slot'2'l through the center portion of one end of the supporting plate and a pair of upstanding lugs 28 spaced laterally from this slot. There is a centering stud 29 extending upwardly from the end opposite the slot 2l and, 55'

in addition, two pair of guide studs 30. For supporting the blade, the supporting blade is provided with transverse ribs 3| extending completely from one side to the other of the comblike guards. These ribs project slightly, as indicated at 32, beyond the lateral or side edge 33 of the supporting plate. Each rib has a knifelike edge 34. At the end 35 of the supporting plate opposite that having the slot, there is a low center section 36, this being in a plane with the main upper surface 31 o the supporting plate. At the opposite end 38 of the supporting plate, that is, the end having the slot 21, there are the pair of raised lugs 28.

Through these lugs extends a pintle pin 40, to which is hinged the clamping plate designated by the assembly numeral 4i. This clamping plate has a pair of depending ears 42 mounted on the pivot pin 4Q. The clamping plate is convexly curved transversely on its upper surface 43 and has a plane or flat lower surface 44. The lower surface is provided with transverse ribs 45, each rib having a sharpened or knife-like edge 46. The ends of the clamping plate each have a pair of downwardly extending lips 41. These lips extend outwardly laterally from the edge 48 of the clamping plate, as indicated at 49 (note Fig. 4) and form a protection against cuts by the corner of the blade. The under side of the clamping plate has a recess 53 in which ts the upper end of the stud 29. There is a circular slot I through the clamping plate slightly opposite from the center, and extending longitudinally from this slot there is a slot 52, the slot extending slightly beyond the center of the clamping plate considered longitudinally.

The device for operating the clamping plate and for clamping this tightly employs a screw 53 having a threaded portion 54 in the threaded section 2| of the bore I8 of the handle. This screw has a projection 55 with an operating head 56, this being shown as hexagonal. A tapered section 51 of the screw leads to a stem 58 extending through the bore I8 and the contracted bore I9 and the perforation 23. There is a collar 5S on the stem and such stem has a head 65 at the top, slightly beveled at 6I on the under side of the head. A cupped sleeve 62 slides in the bore I9 and has a perforation 63 in the base 64, through which the stem above the collar 59 extends. A compression spring 65 is seated in this cup and engages the upper end 66 of the reduced bore I9. An arm 61 is attached to the cupped sleeve 62; this has what might be termed a horizontal section 68 extending through the slot I1 which extends through the section I6 of the handle. An upwardly sloping section 69 leads to a vertical section 1D. This vertical section is provided with a pair of ears 1I, through which extend a pintle 12. A triangularly shaped link 13 is fitted between the ears and engages the pintle.. This link at the opposite end engages a pintle 14 on a pair of depending ears 15 from the clamping plate.

The blade 16 is provided with two opposite cutting edges 11, these terminating at the ends 18. Each end has a pair of notches 19 to accommodate the ears 42 on the under side of the clamping plate. There is a central longitudinal slot 86 extending inwardly from the ends, which ends have projecting portions 8|, which extend slightly beyond the opposite ends of the clamping and supporting plate. At the inner end of each slot 80 there is a transverse slot 82. The slots 82 engage the studs 36 extending upwardly from the supporting plate. The stud 29 lits in one of the slots 80, and the link 13, together with the ears 15 of the clamping plate, extend through the other slot 86. The blade has a central perforation 63 to accommodate the upper portion of the stem 53, this being of suicient size to pass over the head 6.

The manner of using and operating my invention is as follows:

The clamping plate, the stem, and the supporting blade are in the position of Figs. 6 and 8, that is, with the clamping plate in its opened position extending upwardly from one end of the supporting plate. The blade is then placed on the supporting plate with the studs 36 extending through the slots S2, the link 13, and ears being fitted in one of the slots 86, and the stud 29 in the opposite slot B at the end of the blade. The upper portion of the stern extends through the center perforation 83 of the blade. When the device is in this position the screw is threaded in the handle to its limit. This thrusts the head 66 of the stern upwardly considerably. higher than shown in Figs. 2 and 5. The base of the sliding sleeve 62 rests on the collar 59. In order to clamp the blade, the operating head 56 of the screw 53 is rotated to thread the screw outwardly as regards the handle, which action, in lowering the collar 59, permits the spring 65 to force the cupped sleeve 62 downwardly, which action moves the clamping plate 4I from the position of Figs. 6 and 3 to the position of Figs. l through 5. As the clamping plate is lowered, the head 66 and the part of the stem 58 adjacent thereto passes upwardly through the perforation or slot 5I in this clamping plate, and the head engages in the groove 52.

This action brings the knife edges of the ribs on the clamping plate into engagement with the top of the blade directly opposite the knife-like edges of the ribs on the supporting plate. As the screw is tightened, the head 6I! on the uppe' end of the stem 58 exerts a downward pull on the clamping plate and thus clamps the blade tightly between the clamping and the supporting plates. The razor blade and holder are then in position for shaving and, as above described, the attened handle with the grooves I3 and bulbous edges I4 facilitate the holding of the handle in the hand of the person shaving. The downwardlyY extending lips 41 at each corner at the end of the clamping blade cover the corner edges of the blade and lessen the danger of a person cutting himself, when shaving, with these corners. The blade is released by a reverse action, that is, the screw is threaded in the handle, thus raising the stem and the head 66 and bringing the collar 59 against the base of the sleeve 62, elevating this sleeve and compressing the spring 65 at the Sametime. This action moves the arm 61 upwardly and rotates the clamping plate through the medium of the link 13 from the position of Figs. 2 and 5 to that of Figs. 6 and 8.
